Severe Weather Event Summary for June 25, 2024

Fast Facts

• Numerous slow-moving storms occurred from 4:30 PM Tuesday afternoon, June 25, into Tuesday evening. Between 5 and 8:30 PM these storms were at their strongest intensity, producing locally heavy rainfall, scattered damaging winds, scattered large hail, and several tornadoes that were generally not strong but still capable of damage.

• Four tornadoes were confirmed by NWS Storm Damage Survey Teams and additional EMA coordination and using video and photo evidence:
  • ​an EF1 near Preston/Spragueville, IA (Jackson County)
  • an EF0 near Ely, IA (Linn County), and
  • two EF-Unknowns near Olin, IA (Jones County).
• These storms quickly developed stronger, with multiple becoming supercells (meaning they have rotating updrafts) having some characteristics  of more classic tornadoes, especially near Preston/Spragueville, IA.
  • The tornadoes in their early part of their life cycles exhibited traits more so of landspout tornadoes. Landspout tornadoes often:
    • have a narrow, rope-like condensation funnel
    • at times they are translucent or even transparent
    • develop on a well-defined weather boundary (in this case, a nearly stationary front)
    • form while the thunderstorm is still developing​
• Severe straight-line winds of 65+ mph were observed from Iowa City through Muscatine County and into the southwest Quad Cities metro, including with some temporary embedded rotation; scattered wind damage reported.

• Torrential rainfall with slow-moving storms, including amounts as high as 3.30" in Almont, IA in Clinton County, IA and 2.78" in Galva, IL in Henry County.

• Additional information for Central Iowa (NWS Des Moines).
